The fuel delivery system incorporates a low and high pressure circuits to provide the engine with sufficient fuel for all operating conditions.
The low pressure system features the following components:
- Molded plastic saddle type fuel tank
- Fuel pump module (with integral in-tank pump)
- 2 fuel level sensors
- Fuel delivery and return lines
- Fuel filter assembly
The Low Pressure (LP) fuel pump is located in the bottom of the fuel tank assembly. The LP fuel pump has a Direct Current (DC) electric motor and is operated by the LP fuel pump relay. The Body Control Module/Gateway Module (BCM/GWM) controls the LP fuel pump relay. The LP fuel pump draws fuel from the fuel tank and delivers it to the High Pressure (HP) fuel pump. The HP fuel pump is mounted on the engine.
The LP fuel pump also supplies fuel to the 2 jet pumps on either side of the fuel tank. This makes sure there is sufficient fuel in the swirl pot.
The HP system features a Bosch 'common rail' high pressure system.
On vehicles in cold climate markets, a modified fuel pump module is installed on vehicles equipped with a Fuel Fired Booster Heater (FFBH). A FFBH fuel pump is mounted on the right of the fuel tank. A separate fuel line draws fuel from the fuel pump module to the FFBH fuel pump. An additional fuel line delivers the fuel to the FFBH in the engine compartment.
FUEL TANK
ITEM | DESCRIPTION |
---|---|
1 | Fuel pump module |
2 | Vent hose |
3 | Support bracket |
4 | Passive fuel level sensor |
5 | Float - passive fuel level sensor |
6 | Left fuel pick up |
The fuel tank is manufactured using six-layer co-extruded blow-molding technology providing both high mechanical strength and complete emissions integrity. The fuel tank is mounted under the rear seat floorpan, forward of the rear suspension.
The fuel tank is a saddle tank design which is secured to the vehicle floorpan with 2 straps which are bolted in position. The fuel filler neck is produced from stainless steel.
The fuel tank contains a fuel pump module which collects fuel from both sides of the tank. The pump provides the engine fuel demands by supplying the fuel to power the 2 venturi. The rapid flow of fuel through the venturi nozzle creates a depression. The depression draws fuel across the saddle into the pump side of the tank and fills the fuel pump module swirl pot.
An internal bracket allows for the attachment of the left fuel pick-up and the passive fuel level sensor.
An internal breather hose is connected to a stub port passing through the fuel tank casing. An external pipe and hose connect this port to the top of the filler neck. This enables the fuel tank to be filled and controls the fuel cut off during filling.
Fuel level inside the tank is monitored by 2 level sensors.
FUEL PUMP MODULE

10 | Jet pump connection |
11 | Fuel Fired Booster Heater (FFBH) supply connection (if equipped) |
The Powertrain Control Module (PCM) controls the Low Pressure (LP) fuel pump module via the fuel pump relay. The fuel pump relay is located in the Rear Junction Box (RJB).
The LP fuel pump module is located in the right of the fuel tank. The fuel pump module flange is sealed to the tank with an o-ring seal and secured with a retaining ring.
The top flange of the fuel pump module assembly provides the internal and external interface for the tank electrical and fuel connections. The flange is formed with fuel level and fuel pump external electrical connectors. The electrical connectors attach to the active and passive fuel level sensors and the in-tank fuel pump.
The lower part of the LP fuel pump module forms the fuel swirl pot. The swirl pot provides a constant reservoir of fuel for the engine demands.
The High Pressure (HP) fuel pump draws fuel during periods of high demand. At all other times the LP fuel pump supplies the required fuel at a positive pressure.
The fuel is transferred using a venturi pump. The venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section of a pipe. The venturi effect is created by the fuel feed flow from the fuel pump. The rapid flow of fuel through the suction pipe creates a depression. The depression draws the fuel back from the left (passive) side of the fuel tank into the fuel pump (active) side of the fuel tank.
The second venturi effect draws the fuel from the pump side of the fuel tank into the swirl pot. Surplus fuel entering the fuel swirl pot overflows into the usable right of the fuel tank. The LP fuel pump provides sufficient fuel in the swirl pot to feed the HP fuel pump.
Cold climate market vehicles feature a Fuel Fired Booster Heater (FFBH) and an auxiliary fuel pump. The fuel pump module has a separate pipe connection for a fuel supply line that connects to an auxiliary fuel pump. The auxiliary fuel pump locates on the exterior right of the fuel tank. This pipe connection has a sealed suction hose which draws fuel from the swirl pot. An additional fuel line connects the auxiliary fuel pump to the FFBH fuel inlet.
For additional information, refer to:Fuel Fired Booster Heater (412-02 Auxiliary Climate Control, Description and Operation).
FUEL LEVEL SENSORS
There are 2 fuel level sensors to measure the amount of fuel remaining in the left and right sides of the fuel tank. The left passive fuel level sensor 'B' is attached to the tank internal bracket. The right active fuel level sensor 'A' is attached to the outside of the fuel pump swirl pot. Both sensors are connected to the vehicle wiring harness via the external electrical connector on the fuel pump module top flange assembly.
The electrical output signal varies to the amount of fuel remaining in each side of the fuel tank and the position of the float arms. The measured resistance is measured by the fuel level sensors and the information passed to the Body Control Module/Gateway Module (BCM/GWM) assembly. The BCM/GWM implements an anti-slosh function. This monitors the signal and updates the fuel level signal to the instrument cluster at regular intervals. This prevents constant pointer movement caused by fuel movement in the tank due to cornering or braking.
A low level fuel warning indicator is incorporated in the Instrument Cluster (IC). The warning indicator illuminates when the fuel level in the tank falls below a predetermined level.
The fuel level sensor signals are converted into Controller Area Network (CAN) bus messages by the BCM/GWM. The signals are used by the Instrument Cluster (IC) for fuel gauge and fuel warning indicator operation.
The Powertrain Control Module (PCM) monitors the signals. The PCM stores On-Board Diagnostics (OBD) codes. The codes are for mis-fire detection when the fuel level is below a predetermined capacity.
Low Fuel Strategy
When 2.0 liters of useable fuel remain, the engine can be restarted and will run for 60 second intervals. Continuous attempts to re-start the vehicle after the useable fuel has been consumed will cause possible damage to the High Pressure (HP) fuel pump.
The Powertrain Control Module (PCM) is programmed with a strategy which shuts the engine off before the fuel tank runs dry. This is to prevent fuel system damage by air being drawn into the High Pressure (HP) fuel pump.
A low fuel warning is displayed on the Instrument Cluster (IC) when the fuel in the tank reaches approximately 4.0 liters of useable fuel. There is approximately 0.5 liters of un-useable fuel in the tank.
When a further 1.20 liters of fuel is consumed a misfire condition is induced, to again alert the driver to this condition. The misfire will continue until a further 0.8 liters of fuel has been consumed.
The engine will shut down when only 2.0 liters of useable and 0.5 liters of un-useable fuel remain in the tank.
To reset the fuel strategy after engine shutdown, a minimum of 5 liters of fuel must be added to the fuel tank. This must be done when the vehicle is on level ground.
FUEL FILLER PIPE AND BREATHER ASSEMBLY

---|---|
1 | Breather pipe |
2 | Fuel filler cap |
3 | Misfueling protection device (if equipped) |
4 | Fuel filler pipe |
5 | Fuel tank |
6 | Fuel pump module |
The neck of the fuel filler pipe is positioned at the rear of the vehicle, above the rear right wheel. The filler pipe and cap is covered by a molded plastic fuel flap.
The fuel flap has the option to be non-locking or can be electrically locked when the vehicle is locked.
The filler cap is a conventional screw-in type which is secured to the vehicle with a lanyard. The filler cap must be secure to make sure that the tank venting system is sealed and potential fuel loss prevented. The cap has a ratchet locking mechanism. The cap should be screwed-in until 3 audible clicks are heard to make sure it is correctly tightened.
The filler pipe is a stainless steel fabrication which is secured to the vehicle body with 2 brackets and nuts. A metal stub pipe, attached to the filler neck, provides for the attachment of the breather pipe.
The fuel filler pipe attaches to a stub at the rear of the fuel tank which incorporates a check valve. The in-line check valve is mounted inside the fuel tank inlet stub, and is retained in the closed position by a spring. The check valve is only opened when the vehicle is refuelled.
A breather pipe is connected between the fuel filler neck and the fuel tank. The breather pipe enables the fuel tank to be filled, allows for expansion of the fuel vapor and controls the fuel cut off during filling.
MISFUELING PROTECTION DEVICE
ITEM | DESCRIPTION |
---|---|
1 | Filler neck |
2 | Flap |
3 | Reset slots |
4 | Spigots |
5 | Reset tool |
6 | Spring |
The passive misfueling protection device system comprises a mechanically operated flap. The flap is triggered when a smaller diameter filler nozzle is inserted into the misfueling device. A smaller filler nozzle is typically used on petrol (gasoline) pumps.
It is possible to trickle fill fuel into the tank once the passive misfueling protection device has been activated. A noticeable change in fuel filling performance will be experienced with continuous fuel shut-off events significantly reducing the flow of fuel.
The shut off flap is actuated and blocks the sensor port on the fuel pump nozzle, causing it to automatically switch off. The shut off flap is locked in this position by a latch mechanism, once it has been activated.
A reset tool is provided and stored by the spare wheel. The tool is used to reset the misfueling protection device if triggered. The tool is inserted into the filler opening as far as possible with the spigots pointing upper most. When the 2 spigots on the tool are located in the slots it can be pulled outwards. This releases a latch and allows the shut off flap to be opened by its own spring pressure.
The shut off flap is colored yellow so that it is clearly visible within the entrance of the fuel filler pipe when activated. The shut off flap has a 'Handbook' symbol on it.
A 25mm diameter diesel fuel pump nozzle will not activate the misfueling protection device because the nozzle stops against 2 molded lugs. If a 21mm diameter gasoline pump nozzle is inserted into the housing, the smaller diameter allows it to pass the 2 molded lugs. The nozzle strikes 2 pins on the inside of the filler housing which move forward. This movement rotates the shut-off flap which is then held in place by the latch mechanism when the nozzle is removed.
Some markets do not use the petrol fuel guard system and are equipped with a conventional fuel filler pipe neck.

ITEM | DESCRIPTION |
---|---|
1 | Sensing tabs in open state |
2 | Misfueling protection flap open |
The misfueling protection device consists of a mechanically operated flap and 3 fuel nozzle sensing tabs. When a 25mm diameter diesel fuel filler nozzle is inserted into the fuel filler pipe, the 3 sensing tabs push in. This releases the flap into the open position. If a smaller 21mm diameter filler nozzle is inserted in the fuel filler pipe, the 3 sensing tabs will not push in. The flap will not release and blocks the fuel nozzle from entering the filler pipe. The smaller diameter filler nozzle is typically used on petrol (gasoline) pumps.
An adaptor funnel is provided to allow the misfueling device to be temporarily overridden.
This allows a reserve fuel can to be used to refill the vehicle. There are markets where there is no difference in the size of fuel nozzles. The adaptor funnel may be used in those markets.
The adaptor funnel will be located either in the glove compartment or in the luggage compartment alongside the tool kit.
FUEL FILTER ASSEMBLY
ITEM | DESCRIPTION |
---|---|
1 | High Pressure (HP) fuel pump |
2 | Fuel filter |
3 | Fuel cooler |
4 | Pipe filter water drain pipe |
5 | Water In Fuel (WIF) sensor |
The fuel filter canister is located in the engine compartment, and is mounted in a support bracket on the front left suspension turret. The filter canister is manufactured from heat resistant and flame-proof durable plastic, and contains a paper type filter element.
The filter canister incorporates a chamber for collecting moisture. The moisture contained in the diesel fuel collects on the internal filter element and forms droplets, which fall into the moisture chamber. The filter has a Water in Fuel (WIF) sensor. The WIF activates when the maximum recommended level of water in the filter has been reached.
A bleed screw and drain point are located on the filter canister. The bleed screw allows water content in the fuel to be drained off during service intervals.
In cold climate conditions the 'Common rail' High Pressure (HP) injection system works in a Pressure Control Valve (PCV) mode. A pre-heat function re-circulates a quantity of return fuel from the HP fuel system through the filter canister. The fuel re-circulates until a fuel temperature of +40°C is reached. This prevents fuel waxing and improves the engine performance during cold running.
FUEL COOLER
ITEM | DESCRIPTION |
---|---|
1 | Engine coolant connections |
2 | Fuel connections |
The fuel cooler is situated on the engine near the fuel filter.
Engine coolant is used to cool the fuel in the fuel cooler.
The fuel pump in the fuel delivery module receives power via a fuel pump relay in the Rear Junction Box (RJB). The Body Control Module/Gateway Module (BCM/GWM) assembly controls the fuel pump relay.. The fuel pump relay is active when the ignition is in all power modes except for Power Mode 0 (vehicle locked and armed).
The PCM connects to the BCM/GWM assembly to receive a 'wake-up' message. In the event of an accident, the Restraints Control Module (RCM) outputs a crash signal. The crash signal goes to the BCM/GWM assembly to disable the fuel pump relay.
Inside the fuel tank there are 2 fuel level sensors, which output signals to the BCM/GWM for fuel tank fuel level. The BCM/GWM processes this information and sends it to the Instrument Cluster (IC). The IC displays the remaining fuel level and low fuel warning.

-
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
-
When measuring fuel sender resistance values with a multimeter, it is critical to use the correct multimeter setting. The multimeter should NOT be on the 'Auto' setting and MUST be set to 'Manual'. This will help prevent incorrect diagnosis and unnecessary replacement of fuel senders. If the multimeter range is set at 'Auto' then, during a sweep of the sender from 50 Ohms to 998 Ohms, the multimeter has to change its measurement range. For approximately 1 second, during the range switch over point, the multimeter display indicates an open circuit. This can lead to a mis-diagnosis of a fuel sender fault.

There are two variants of speed control available; a standard system and an adaptive system. The standard system maintains a set speed selected by the driver until operation is suspended or cancelled by a further input from the driver. The adaptive system includes the same functionality as the standard system, and has the following additional functions:
- Follow Mode: Reduces vehicle speed, to less than the set speed, in order to maintain a selected distance behind a slower moving vehicle, then resumes the set speed once the way ahead is clear
- Queue Assist: Stops the vehicle a set distance behind the vehicle in front if it comes to a halt. When the vehicle in front moves away, a brief press of the accelerator pedal resumes adaptive speed control operation
- Forward Alert: Alerts the driver when rapidly approaching a slower moving vehicle
- Advanced Emergency Brake Assist: Partially applies the brakes in preparation for a sudden braking action, to improve brake response
- Intelligent Emergency Braking: Applies the brakes to reduce the impact velocity if a collision is unavoidable.
The standard speed control system is controlled by the ECM (Engine Control Module) and switches on the right steering wheel switchpack. The adaptive speed control system is controlled by the ECM, the switches on the right steering wheel switchpack and the ASCM (Adaptive Speed Control Module). Both systems also use the:
- Brake pedal switch.For additional information, refer to:Braking Control System (206-11 Brake Controls, Description and Operation).
- APP (Accelerator Pedal Position) sensor. For additional information, refer to:
Electronic Engine Controls (303-14A Electronic Engine Controls - TDV6 3.0L Diesel /TDV6 3.0L Diesel - Gen 1.5/TDV6 3.0L Diesel - Gen 2, Description and Operation),Electronic Engine Controls (303-14B Electronic Engine Controls - V6 S/C 3.0L Petrol, Description and Operation),Electronic Engine Controls (303-14C Electronic Engine Controls - V8 S/C 5.0L Petrol, Description and Operation),Electronic Engine Controls (303-14D Electronic Engine Controls - TDV8 4.4L Diesel, Description and Operation).
- ABS (Anti-lock brake system) control module. For additional information, refer to:Braking Control System (206-11 Brake Controls, Description and Operation).
- TCS (Transmission Control Switch). For additional information, refer to:Transmission Description (307-01A Automatic Transmission/Transaxle - Vehicles With: 8HP70 8-Speed Automatic Transmission AWD, Description and Operation).
- TCM (Transmission Control Module). For additional information, refer to:Transmission Description (307-01A Automatic Transmission/Transaxle - Vehicles With: 8HP70 8-Speed Automatic Transmission AWD, Description and Operation).
- Terrain Response® switchpack. For additional information, refer to:Ride and Handling Optimization (204-06 Ride and Handling Optimization, Description and Operation).
- Instrument Cluster (IC). For additional information, refer to:
Instrument Cluster (413-01 Instrument Cluster, Description and Operation),Information and Message Center (413-08 Information and Message Center, Description and Operation).
During speed control operation, the ECM controls vehicle speed by adjusting the engine throttle and fuel injection. The adaptive speed control system also uses the ASCM to scan the road ahead and, if necessary, signal the ABS control module to apply the brakes to slow the vehicle.
All vehicles also incorporate an ASL (Automatic Speed Limiter) system. When a speed has been set, the engine will respond normally up to the set speed. Further accelerator pressure will not increase the speed beyond the set speed unless sudden, rapid acceleration (kickdown) is applied. The ASL system is controlled by the ECM, the speed control switches on the right steering wheel switchpack and an ASL switch.
The ASL system and the speed control system cannot be used simultaneously. The system in use when the ignition is turned off is automatically enabled when the ignition is turned back on. However the speed settings are not remembered and will have to be set again.

The standard speed control switches are located on the right steering wheel switchpack. The switches are resistive ladder type switches which vary the resistance of a 5 volt signal sent to them. The resistive ladder is wired to a LIN (Local Interconnect Network) node which transmits the data to the CJB (Central Junction Box) via the clockspring. The CJB then transmits the data on the high speed CAN (Controller Area Network) Powertrain bus.

1 | Set + (engage/accelerate) switch |
2 | RES (resume) switch |
3 | Time gap decrease switch |
4 | - (decelerate) switch |
5 | CANCEL switch |
6 | Time gap increase switch |
The adaptive speed control switches are the same as used for standard speed control, with the addition of two time gap switches. The time gap switches allow the driver to adjust the follow mode and forward alert functions to one of four pre-set time gaps (gap 1 = 1 second; gap 2 = 1.4 seconds; gap 3 = 1.8 seconds; gap 4 = 2.2 seconds). The selected time gap is displayed in the message center when the time gap switches are operated.
When adaptive speed control is engaged, the switches adjust the follow mode time gap. When adaptive speed control is disengaged, the switches adjust the forward alert time gap (provided forward alert is enabled in the instrument cluster menu). The follow mode function defaults to the gap 3 setting each time the ignition is switched on. The forward alert function recalls the last selected time gap when the ignition is switched on.
ADAPTIVE SPEED CONTROL MODULE
ITEM | DESCRIPTION |
---|---|
1 | Adaptive Speed Control Module (ASCM) |
2 | Mounting bracket |
3 | Adjuster screw |
The ASCM is attached to a bracket located in the armature of the front bumper, to the right of the vehicle centerline. A foam block in the bumper armature eliminates radar signal reflections within the armature.
The ASCM contains a forward looking radar transceiver together with related controlling hardware and software. A high speed CAN Powertrain bus connection allows the ASCM to communicate with other system control modules. Power supplies to the ASCM are from the extended ignition relay in the RJB (Rear Junction Box) and the ignition relay in the EJB (Engine Junction Box).
The adaptive speed control module is active whenever the ignition is on, even if speed control is not engaged, in order to operate the forward alert, advanced emergency brake assist and intelligent emergency braking functions. With the ignition on, the adaptive speed control module is powered up but no radar transmissions are emitted until the vehicle is in motion.
The adaptive speed control module transmits a radar beam forward of the vehicle and detects the returning signals reflected off other vehicles and objects ahead. The radar beam is electronically scanned at a rate of 20 sweeps/second across a total arc of 20° centered on the longitudinal axis of the vehicle. The radar operates at millimetric wavelengths (76 - 77 GHz) and transmits a frequency modulated continuous wave signal at a relatively low power level (no high power pulses). The control module detects the range, relative velocity and angle of objects within the scanned arc for up to a distance of approximately 130 meters (426.5 feet).
The ASCM compares vehicle speed data from the ABS control module with the relative speed of an external object as detected by the radar to ascertain whether the object is stationary or not. If tires are fitted which are different in diameter from those specified for the vehicle, the vehicle speed, calculated by the ABS module, will not be the true road speed. This situation may cause stationary objects to be falsely identified as moving vehicles and result in automatic deceleration on a clear road.
The ASCM continuously monitors both moving vehicles and stationary objects to determine if it can 'see' normally. If the control module can detect only a few objects, because it is physically blocked (for example by an accumulation of snow or mud on the lower grill of the front bumper, or an incorrectly located number plate), or there are few roadside objects or other vehicles in the area, it may determine that it is blocked. The control module then inhibits adaptive speed control and records a DTC (Diagnostic Trouble Code). The system will reset after the ignition is cycled. In this case the control module is not faulty and should not be replaced.
If the ASCM is replaced in service it must be mechanically aligned vertically. Horizontal alignment is achieved by putting the control module into service mode using approved Land Rover diagnostic equipment. The vehicle then needs to be driven for a short period while the control module calibrates itself. Calibration is complete when the follow mode warning indicator in the instrument cluster stops flashing.For additional information, refer to:(310-03D Speed Control - TDV8 4.4L Diesel)
AUTOMATIC SPEED LIMITER
ASL SWITCH
The ASL switch is integrated into the Terrain Response® switchpack in the floor console. An amber LED (Light Emitting Diode) in the ASL switch remains illuminated while the ASL is selected on. Selection of the ASL switch is transmitted on high speed CAN Chassis bus from the Terrain Response® switchpack to the ECM through the GWM (Gateway Module), since the ECM is connected to the high speed CAN Powertrain bus.
INSTRUMENT CLUSTER WARNING INDICATORS
SPEED CONTROL WARNING INDICATOR
The speed control warning indicator illuminates when standard or adaptive speed control is engaged.
FOLLOW MODE WARNING INDICATOR
The follow mode warning indicator illuminates when the adaptive speed control system is engaged and goes into follow mode. When the system is engaged, the time gap setting is displayed in the message center in the form of a vehicle with 1 to 4 bars in front of it, where the number of bars correspond to the current time gap setting.
FORWARD ALERT WARNING INDICATOR
The forward alert warning indicator illuminates if forward alert is enabled in the IC menu.
ASL WARNING INDICATOR
The speed control warning indicator illuminates when ASL is selected on and a speed limit is set in the message center.
For standard or adaptive speed control to engage, the vehicle must be in the following configuration:
- Transmission in D (drive)
- Transfer case in high range
- Terrain Response® in the general (special programs off) or grass/gravel/snow program
- HDC (Hill Descent Control) off
- ASL off
- Traveling at 20 mph (32 km/h) or more.
STANDARD SPEED CONTROL
ENGAGE SPEED CONTROL
Speed control is engaged by pressing the SET + switch. On receipt of the switch input, the ECM adopts the current vehicle speed as the speed control set speed. When speed control is engaged, the IC illuminates the speed control warning indicator and the set speed is displayed in the message center.
The set speed is cleared when the ignition is switched off or if the speed control system develops a fault.
SET SPEED ADJUSTMENT
Once engaged the set speed can be increased by one of 3 methods:
- Press and hold the SET + switch which will cause the vehicle to accelerate. When the switch is released the attained speed will be the new set speed.
- Repeatedly pressing the SET + switch. Each press increases the vehicle speed by 1 mph (2 km/h).
- Use the accelerator pedal to increase the vehicle speed. Once the required speed is reached, a single press of the SET + switch will set the cruise speed.
The set speed can be reduced by pressing and holding the decelerate - switch until the required speed is reached. When the switch is released the speed is reset at that value. The set speed can be reduced incrementally by pressing and releasing the decelerate - switch. Each press will reduce the speed by 1 mph (2 km/h).
Speed control adjustment is limited around the current vehicle speed. This means speed adjustment won't occur when resuming or if the vehicle speed is noticeably different to set speed. This is noticeable when resuming speed control and a large difference exists between the set speed and the current speed. The driver can set a new speed, but can't adjust the old speed.
SUSPENDING SPEED CONTROL
Suspending speed control means speed control has been deactivated without loss of the set speed. Speed control is suspended when one of the following occurs:
- Vehicle speed falls below 20 mph (32 km/h)
- The brake pedal is pressed
- The CANCEL switch is pressed
- N (neutral), R (reverse) or P (park) is selected on the TCS
- The EPB (Electric Park Brake) is applied
- If the accelerator pedal is used to accelerate beyond the set speed for too long (more than 5 minutes)
- Engine speed too high (cancel limit set just below red line)
- The ABS control module activates ETC (Electronic Traction Control) or DSC (Dynamic Stability Control)
- HDC is selected
- Terrain Response® adopts a special program other than grass/gravel/snow
- The transfer case is selected to low range.
RESUMING SPEED CONTROL
A single press of the RES switch will resume speed control at the memorized set speed.
ADAPTIVE SPEED CONTROL
Adaptive speed control system is not a collision warning or avoidance system. At all times the driver must be prepared to intervene to control the vehicle speed.
Adaptive speed control operation is similar to the standard speed control system for engaging, suspending and resuming speed control. The main differences between the two systems is that adaptive speed control remains engaged below 20 mph (32 km/h) and uses the brakes to slow the vehicle, to a halt if necessary.
If adaptive speed control is suspended by pressing the CANCEL switch or the brake pedal, it can be re-engaged by pressing the RES switch once vehicle speed is above 7 mph (11 km/h).
SYSTEM RESTRICTIONS
The adaptive speed control system is only intended to provide enhanced speed control in certain restricted conditions. The following illustration shows circumstances where the adaptive speed control system may brake late or unexpectedly. The driver is required to intervene in these situations.
- Driving on a different line to the vehicle in front.
- Vehicles that merge into the same lane are only detected once they have moved fully into the lane.
- On bends in the road there can be issues with detection of the vehicle in front when going into and coming out of a bend.
- Moving around a stationary vehicle may cause uncertainty as to which vehicle is being followed.
- A vehicle in front moving out of your lane may cause uncertainty as to which vehicle is being followed.
On the approach to, or exit from a bend, a target vehicle may be lost or a new target acquired as vehicles ahead change their angular position with respect to the adaptive speed control module. On a straight road, if the sensing vehicle is in follow mode below its selected set speed, losing the target vehicle will cause the sensing vehicle to accelerate to this set speed. This acceleration is undesirable either on, or entering a bend when the target is suddenly lost, and in this situation the system inhibits the resumption of the set speed.
FOLLOW MODE
A set speed is selected in the normal speed control manner and this speed is maintained until a slower vehicle is encountered in the lane ahead. When the vehicle ahead comes within the effective range of the radar, the system identifies it as a target vehicle. To indicate that the system is in follow mode, the follow mode warning indicator illuminates. When the distance between the two vehicles closes to the set time gap, the adaptive speed control system reduces engine speed and, if necessary, applies the brakes to maintain the set time gap.
Automatic braking is limited to approximately 30% of full pressure (0.3 G deceleration) and is intended to provide a smooth, gradual deceleration in follow mode conditions.
Follow mode is effectively a closed loop system. If several vehicles are ahead, the closest vehicle is chosen as the target to follow. If the target vehicle moves out of radar range, or if either vehicle changes lane, the system exits follow mode and extinguishes the follow mode warning indicator. The adaptive speed control system then increases vehicle speed back to the original set speed.
QUEUE ASSIST
When adaptive speed control is engaged, if the target vehicle comes to a halt the ASCM reduces engine speed and applies the brakes to halt the sensing vehicle and suspends speed control operation. The control module also applies the EPB if one of the following occurs:
- Adaptive speed control is disengaged with the CANCEL switch
- The vehicle is stationary for more than 2 minutes
- Driver exit is detected (assumed if the driver seatbelt is unbuckled and the driver door is opened)
- A system fault is detected.
When the target vehicle moves away, pressing the accelerator pedal for a minimum of 0.5 second resumes speed control operation. The sensing vehicle then follows the target vehicle in follow mode or until it stops again, or, if it can no longer detect a target, accelerates back up to the set speed.
FORWARD ALERT
If an object is detected close ahead, a warning tone will be emitted and a message will be displayed. The brakes will not be applied.
The forward alert system is active when the warning indicator in the instrument cluster is illuminated. Forward alert does not initiate any action, the driver must take the appropriate action when the message is displayed. The system monitors driver intervention and may not issue the warning if the driver has taken the appropriate action (braking, steering or indicating) early enough.
The sensitivity of the warning can be changed using the gap increase and decrease switches when the adaptive cruise control is not engaged. Confirmation of the gap change is given in the message center.
Forward alert can be switched on or off using the instrument cluster menu.
ADVANCED EMERGENCY BRAKE ASSIST
Advanced EBA (Emergency Brake Assist) improves braking response during emergency braking, and is an enhancement of the electronic brake prefill and emergency brake assist functions controlled by the ABS control module.For additional information, refer to:Braking Control System (206-11 Brake Controls, Description and Operation).
With advanced EBA, if the risk of a collision increases after the vehicle passes the forward alert activation threshold, the ASCM signals the ABS control module to activate the electronic brake prefill and emergency brake assist functions. With advanced EBA, the electronic brake prefill function operates in two stages:
- Stage 1:
- Applies a brake pressure of approximately 3 bar (43.5 lbf/in²) to all of the brakes
- Lowers the EBA activation threshold in the ABS control module
- Signals the CJB on the high speed CAN bus to activate the stop lamps
- Stage 2 increases the brake pressure to approximately 10 bar (145 lbf/in²).
Stage 1 is activated if the collision risk increases to a level considered as credible, with the accelerator pedal pressed. Stage 2 is activated when the accelerator pedal is released during an imminent risk of collision. If the accelerator pedal has already been released when the collision risk increased to the credible level, the two stages of electronic brake prefill are activated simultaneously, to give an immediate brake pressure of 10 bar (145 lbf/in²).
While the second stage of electronic brake prefill is active, if the brake pedal is then pressed quickly, the ABS control module activates EBA, even if only light pressure is applied to the pedal.
Advanced EBA is available at vehicle speeds above 5 mph (7 km/h) and will function even when forward alert and adaptive cruise control are switched off.
If a fault occurs in the system a related message is displayed in the message center. Advanced EBA will not be available until the fault is rectified.
INTELLIGENT EMERGENCY BRAKING
Intelligent emergency braking reduces the impact velocity if the adaptive speed control module determines that a collision is unavoidable, even with driver intervention. It is not designed to prevent accidents from occurring. Typical activation of intelligent emergency braking is approximately 0.8 second before impact. During this 0.8 second period the speed of the sensing vehicle is reduced, thus reducing the impact energy.
If the ASCM determines a collision is unavoidable, it signals the ABS control module to apply emergency brake pressure to all of the brakes. On vehicles without active safety belts, emergency brake pressure is 50 bar (725 lbf/in²) maximum. On vehicles with active safety belts, emergency brake pressure is 100 bar (1450 lbf/in²) maximum.
When intelligent emergency braking is initiated the ASCM also signals the RCM (Restraints Control Module) to fire the front seatbelt retractors.For additional information, refer to:Seatbelt System (501-20A Seatbelt System, Description and Operation).
After the intelligent emergency braking function has activated, it is then disabled, as the vehicle is assumed to be damaged. After the vehicle has been repaired, the intelligent emergency braking function can be re-enabled using Land Rover approved diagnostic equipment.
The intelligent emergency braking function operates at vehicle speeds down to zero, and will function even when forward alert and adaptive cruise control are switched off.
If the intelligent emergency braking feature is disabled for any reason, a related message is displayed in the message center.
AUTOMATIC SPEED LIMITER
With the ASL switch selected on, the ASL system can be operated in a similar manner to the cruise control system. A speed limit between 18 and 150 mph (30 and 240 km/h) can be set, with the vehicle stationary or moving, using the speed control SET + and - switches (in ASL operation, the SET + and the - switches change the set speed limit in steps of 5 mph (8 km/h), instead of the 1 mph (2 km/h) steps of the cruise control system). The ASL warning indicator illuminates and the set speed limit is displayed in the message center.
If the vehicle reaches the set speed limit, the ECM intervenes to govern vehicle speed at the set speed limit.
In certain conditions, such as a steep downhill gradient, the vehicle speed may exceed the set speed limit. This is because engine braking is unable to maintain or reduce the vehicle speed.
The ASL can be disengaged and re-engaged using the speed control CANCEL and RES switches respectively. ASL also disengages if kickdown is used on the accelerator pedal. Pressing the ASL switch cancels ASL operation and the speed limit will need to be reset the next time the switch is selected on.
